First plastic rear axle transmission crossbeam debuts at Mercedes

07/16/2015

ContiTech Vibration Control and BASF have teamed together to develop the world's first plastic transmission crossbeam for use in the rear axle subframe of the S-Class from Mercedes-Benz. The component is molded Ultramid A3WG10 CR polyamide from BASF, which is reinforced and optimized to withstand high mechanical loads.

Compared to the previous beam made from die-cast aluminum, this highly durable component offers a weight saving of 25%, better acoustics as well as excellent mechanical properties, even at high temperatures, and conforms to the latest crash requirements. The design expertise of BASF's simulation tool Ultrasim also made a major contribution to these properties.
